Physics P1.2 0.0 / 5 ? PhysicsEnergyGCSEAQA Created by: emily13566Created on: 11-10-16 18:04 What is kinetic energy? Energy in moving objects. 1 of 10 What is electrical energy? Energy in moving charges or static electric charges. 2 of 10 What is elastic potential energy? Energy in stretched or squashed objects. 3 of 10 What is chemical energy? Energy stored in fuel, foods and batteries. 4 of 10 What is Gravitational potential energy? Energy stored in raised objects. 5 of 10 What important fact does the conservation of energy tell us? Energy can't be created or destroyed. 6 of 10 What is 'useful energy'? Is energy transferred to where it's wanted, in the form it's wanted in. 7 of 10 What is 'wasted energy' and what happens to it? Energy that's not usefully transferred and it will then be transferred to the surroundings. 8 of 10 What is the equation for efficiency? Efficiency = useful energy transferred / total energy supplied (*100) 9 of 10 Why can't a machine be more than 100% efficient? Because we can't get more energy than we put in. 10 of 10
